You could resharpen the cutters by lapping the flat side on some 1000 grit sandpaper. You could resharpen as necessary with no noticeable change in the profile. With MLCS, you get what you pay for. You go with a bargain basement HSS bit, you get very short life, you spend on one of their more expensive carbide-tipped items, or the Katana bits, and they are significantly better.
